Outline of Final Research Achievements |
We have investigated to realize nano-Raman imaging on: (1) flocculation method to elucidate hydrated metal ions, interaction with metal nanoparticles via thiol molecules possessing polar functional groups, and to clarify the effect of surface residuals of citrate ions on adsorption of DNA and RNA bases. (2) gap mode plasmon to achieve single molecule detection and also spatial resolutions. We found that: (2-1) various metal species like iron, nickel and aluminum as well as Au, Ag and Cu provided enormous Raman enhancement of 108-1010, (2-2) laser trapping for AgNPs in suspensions, (2-3) photocatalytic oxidation of p-alkyl thiophenol on Ag films. Conclusively, our project proceeded quite efficiently towards nano-Rama imaging.
